There is no economic reason for Osborne’s surplus plan. It’s time Labour stopped playing catch-up

When George Osborne imposed tough fiscal austerity in his first two years as Chancellor, he at least had an excuse. He could point to Greece and say: we must do whatever it takes to avoid that fate. Many economists at the time argued that eurozone countries were rather different from the UK, and we now understand much better why having your own central bank is the critical difference. But back in 2010 there were many who were worried by what was happening in the eurozone and supported the spirit if not the detail of Osborne’s plans.

Five years later, and the Chancellor wants to repeat the experience of those first two years by making it unlawful for the government to run budget deficits in normal times. On this occasion he has no excuses: there is no chance the UK will become like Greece. Seventy-nine economists have already written a letter denouncing the surplus plan, and both the Financial Times and the Economist have joined the criticism.

Why are economists against the idea? The Chancellor wants to bring government debt down rapidly. Yet economic theory is pretty clear that if you want to reduce government debt, it is generally best to plan to do this slowly. The costs of raising taxes or cutting spending today can easily exceed the future benefits that come from having to pay less interest because debt is lower.

However, Osborne rarely appeals to economic theory when it comes to fiscal policy, preferring household analogies involving credit cards. Yet even this does not work for him. We should pay off credit cards quickly because interest rates on credit-card debt are very high. In contrast, interest rates on UK government debt are historically low. Any business will tell you that the best time to invest is when borrowing is cheap. Now is the time to borrow to improve the UK’s infrastructure, but in order to achieve its surplus target the government plans to spend less on public investment than at any time over the past 12 years. So, how does the Chancellor justify going for surpluses? One argument is an old favourite of those advocating austerity: reducing the burden on future generations. Yet intergenerational equity hardly justifies reducing debt rapidly. Those who have suffered the most from the Great Recession are the young and it is they who will bear the cost of going for surpluses.

The second argument the Chancellor uses is that we need to be prepared for an uncertain future. It is important to decode what this means. He is not talking about a possible recession in the next few years, because the economics goes completely the other way. As the governor of the Bank of England, Mark Carney, has said, going for surplus will be a big drag on growth. He may be able to offset this by keeping interest rates low, but if other things go wrong the Bank will run out of ammunition. Going for surplus increases the chances of a downturn in the next few years, which is another reason why Osborne’s plans have angered many economists.

The risk that the Chancellor probably has in mind is not a mild economic downturn but another major crisis, like a new global financial crash. He wants the government to be able to run up large deficits in such a crisis and to have the resources to be able to bail out financial institutions once again. (The Conservatives may say the 2010 deficit was down to Labour profligacy but Osborne knows that is not true.) However, presumably the Chancellor also thinks that the banking measures he has implemented should prevent such a crisis happening in the next decade or two, so we are talking about something 30 or 40 years hence. In that case we do not need budget surpluses: modest deficits will be sufficient to cut the current debt-to-GDP ratio by half in 30 years’ time.

There is a quite different explanation for why Osborne is so keen to get to a budget surplus quickly. It is a great excuse for reducing the size of the state, particularly when you have pledged not to raise most taxes. Politically, this is best done quickly, to be well clear of the next election. This was what happened from 2010 to 2015: sharp austerity, followed by much more modest cutbacks and tax breaks. Even though the economy suffered as a result, he still won the election, so why not do it again?

How will Labour respond to Osborne’s surplus strategy? Some MPs want to capitulate completely: say they overspent before the recession and follow Osborne’s lead today. That is a frightening prospect, because it would leave the SNP as the only major party talking any sense about UK fiscal policy. (Ironically, this is the same party that tries to pretend, against all the evidence, that the immediate fiscal position of an independent Scotland would not be dire.)

The problem for Labour is that it keeps on making the same mistake on fiscal policy, which is to triangulate between sensible macroeconomics and what works well in focus groups. Just before and after the 2010 defeat, it should have made the positive case for ensuring recovery before worrying about debt. Instead, the message of “too far, too fast” just sounded like “austerity-lite”. And crucially, it failed to counter the narrative of past Labour profligacy, preferring to “move on”.

It is time for Labour to change the strategy to something completely different – to start telling the truth. To say that managing the government’s finances is different from running a household budget and that the deficit fetishism of the past five years has damaged the economy. Only that way can it avoid being tagged in five years’ time as the party that is always fiscally irresponsible.

David had taken the same tablets for years. Why the sudden side effects?

David had been getting bouts of faintness and dizziness for the past week. He said it was exactly like the turns he used to get before he’d had his pacemaker inserted. A malfunctioning pacemaker didn’t sound too good, so I told him I’d pop in at lunchtime.

Everything was in good order. He was recovering from a nasty cough, though, so I wondered aloud if, at the age of 82, he might just be feeling weak from having fought that off. I suggested he let me know if things didn’t settle.

I imagined he would give it a week or two, but the following day there was another visit request. Apparently he’d had a further turn that morning. The carer hadn’t liked the look of him so she’d rung the surgery.

Once again, he was back to normal by the time I got there. I quizzed him further. The symptoms came on when he got up from the sofa, or if bending down for something, suggesting his blood pressure might be falling with the change in posture. I checked the medication listed in his notes: eight different drugs, at least two of which could cause that problem. But David had been taking the same tablets for years; why would he suddenly develop side effects now?

I thought I’d better establish if his blood pressure was dropping. I got him to stand, and measured it repeatedly over a period of several minutes. Not a hint of a fall. And nor did he now feel in the slightest bit unwell. I was stumped. David’s wife had been watching proceedings from her armchair. “Mind you,” she said, “it only happens mid-morning.”

The specific timing made me pause. I asked to see his tablets. David passed me a carrier bag of boxes. I went through them methodically, cross-referencing each one to his notes.

“Well, there’s your trouble,” I said, holding out a couple of the packets. One was emblazoned with the name “Diffundox”, the other “Prosurin”. “They’re actually the same thing.”

Every medication has two names, a brand name and a generic one – both Diffundox and Prosurin are brand names of a medication known generically as tamsulosin, which improves weak urinary flow in men with enlarged prostates. Doctors are encouraged to prescribe generically in almost all circumstances – if I put “tamsulosin” on a prescription, the pharmacist can supply the best value generic available at that time, but if I specify a brand name they’re obliged to dispense that particular one irrespective of cost.

Generic prescribing is good for the NHS drug budget, but it can be horribly confusing for patients. Long-term medication keeps changing its appearance – round white tablets one month, red ovals the next, with different packaging to boot. And while the box always has the generic name on it somewhere, it’s much less prominent than the brand name. With so many patients on multiple medications, all of which are subject to chopping and changing between generics, it’s no wonder mix-ups occur. Couple that with doctors forever stopping and starting drugs and adjusting doses, and you start to get some inkling of quite how much potential there is for error.

I said to David that, at some point the previous week, two different brands of tamsulosin must have found their way into his bag. They looked for all the world like different medications to him, with the result that he was inadvertently taking a double dose every morning. The postural drops in his blood pressure were making him distinctly unwell, but were wearing off after a few hours.

Even though I tried to explain things clearly, David looked baffled that I, an apparently sane and rational being, seemed to be suggesting that two self-evidently different tablets were somehow the same. The arcane world of drug pricing and generic substitution was clearly not something he had much interest in exploring. So, I pocketed one of the aberrant packets of pills, returned the rest, and told him he would feel much better the next day. I’m glad to say he did.
